Definitions

• the present invention relates generally to compositions and methods for treating aged or environmentally damaged skin.
• the present invention is directed towards compositions and methods for their use comprising a combination of compounds that can improve the physiological function of the skin, the metabolism of the skin, and/or the physical appearance of the skin.
• One approach involves the use of specific agents to directly stimulate or inhibit selected biochemical targets. Examples include the use of retinoids to stimulate collagen and glycosaminoglycan synthesis by fibroblasts (Schiltz, et al., 1986).
• Another approach is to use agents or processes that stimulate the rate at which the epidermis replaces itself, a process known as epidermal cell renewal. Increases in epidermal cell renewal rates usually result from a more rapid rate of replication of epidermal basal cells, and can be caused by diverse stimuli such as chemical or physical injury, adverse environmental conditions, or direct stimulators of basal cell division.
• Some examples of chemical injury include allergic responses or non-allergic contact irritation, pH extremes, or interaction of the stratum corneum with household or industrial chemicals or pollutants.
• Physical injury can include skin abrasion, friction (i.e. on the soles and heels of the feet), or removal of the stratum corneum by physical exfoliation (e.g., cosmetic masks) or by tape stripping.
• Agents that directly or indirectly stimulate basal cell division include hydroxy acids, retinoids, or barrier disrupters.
• U.S. Pat. No. 5,720,963 discloses that a combination of hydroxy acids, retinoids, and cerebrosides causes chronic injury to the stratum corneum and results in epidermal and dermal repair of the structurally-deteriorated skin.
• No. 6,495,126 uses a combination of surfactants and chelating agents to stimulate an endogenous stratum corneum chymotryptic proteinase that causes a loosening of corneocytes, resulting in an increased rate of epidermal replacement and chronic anti-aging benefits.
• Adverse environmental exposures that can result in more rapid epidermal turnover rates include UVA, UVB, and IR radiation from the sun and cold coupled with low relative humidity (i.e. low dew point).
• the present invention overcomes deficiencies in the art by providing compositions and methods for their use that can be used to treat aged, mature, nutritionally-compromised, and/or environmentally-damaged skin.
• compositions comprising ximenynic acid, niacin, alpha-lipoic acid, and/or a mushroom extract, or any combination thereof, wherein the composition is formulated as a cosmetic blend.

• Ximenynic acid is a conjugated, unsaturated fatty acid found in the seeds of the sandalwood.
• Essential unsaturated fatty acids, including omega-3 and omega-6 essential fatty acids are important to the structure and function of the stratum corneum barrier. Women of a number of African tribes use it in the form of a mask that assists with wound healing. It also reinvigorates and firms the skin.

• Alpha lipoic acid has been called the universal anti-oxidant since it is able to quench both lipid and water soluble free radicals. It is normally present in the cell in small quantities. It serves as a co-enzyme in sugar metabolism, but is also available to serve as an anti-oxidant when present in higher concentrations.
